Thanks for the link. Very impressive.
All I need is the body to be a bird instead.
I think I will have to look at creating one myself. I remember there was at least one thread in the old forums that dealt with the techniques needed to create a centaur. I will have to hunt them up. At that time I was more interested in putting an animal head on a human body (unsuccessfully).
Can you give us a sketch or two of what you want? I notice that descriptions can sometmes result in lots of confusion and lost time hashing out what the searcher really needs.
Just please be aware, you might still have to do some frankensteining of your own.
